note:
①Do not use the computer USB supply for the camera,because most computer USB 2.0 output voltage is 5V,But the current is less than 500mA.
② Some mobile phone / tablet usb charger with identification resistance, can not identify the camera, the current can not meet the requirements, it is not recommended.
③ Since the camera itself does not support the fast charging function, some USB ports with fast charging function can't start the quick charging mode of 5V 2.4A-3A, resulting in insufficient power supply. Recommended for normal mode 2.4A, 3A is be better.
④The 5V3A power adapter is suitable for long video recording on the camera. Due to the fact that when you press the shutter button to take a picture, the USB power supply is required to have a large instantaneous power, some models may not work properly, please replace other high-quality high-power external power supply.
